1,Q: What makes the BFU Bottom-Access FFU ideal for ISO Class 3-6 cleanrooms?
A: This FFU combines large-capacity HEPA filtration (H13/H14, 99.95–99.995% @ 0.3µm) with a 1220x620mm airflow footprint, ensuring uniform ISO compliance in pharmaceutical and semiconductor facilities. Its bottom-access design allows maintenance without disrupting laminar airflow—critical for high-cleanliness zones.
2,Q: How does the tool-free filter replacement work, and what are the time savings?
A: The patented bottom-access panel eliminates ceiling dismantling. Replace filters in under 5 minutes (vs. 30+ minutes for traditional FFUs), reducing labor costs by 60%. A slide-lock mechanism ensures airtight resealing post-maintenance.
3,Q: Can this energy-efficient FFU integrate with existing cleanroom HVAC systems?
A: Yes, the EC motor’s Modbus RTU/PROFINET compatibility allows seamless BMS integration. Real-time airflow adjustments cut energy use by 30% while maintaining ISO airflow velocity standards (0.45 m/s ±10%).
